78-09: Chlorine Dixide Use in Cooling Systems Using Sewage Effluent as Make-upWhen the City of Burbank engineers decided in 1967 to use sewage plant effluent for cooling tower makeup without removing the phosphate and without final filtration, it was a bold decision. Although there were many installations utilizing sewage plant effluent for cooling and even some for boiler water makeup, these installations pretreated with lime to remove the phosphate from the water.

By performing thorough annual inspections as described

not only of the subject cooling system

energy consumption

This document's objective is to provide owners

Criteria for filtration selection will also be shared

These two groups of components require the most attention because they will deteriorate rapidly if preventive measures are not taken

and a consequent reduction or complete elimination of microbiologically-induced corrosion

The plant chemical processes are cooled by 3 mechanical draft-cooling towers with a combined recirculation rate of 267

This paper reviews this situation in view of the continuing difficulty in obtaining proper penetration of the recommended salt treatments

Improving worker safety

The CTI ATC-105 test code is the most frequently cited document produced by Performance and Technology Committee of the Cooling Technology Institute

cooling tower basins and other industrial water tanks are cleaned during facility-wide outages and involve dangerous confined space entry and lengthy procedures
